Embodiment 1
[0013] Crush the dried fruit shell to 0.15mm~30.00mm, weigh it for later use. Configure phosphoric acid solution with a mass fraction of 25%. The weighed fruit shell was mixed with the phosphoric acid solution according to the impregnation ratio of 1:2, and left to stand for 2 hours to obtain the mixture A. Weigh phenol equivalent to 1 / 10 of the weight of mixture A and mix it with mixture A, put it in a 105°C drying oven, and dry it for 12 hours to obtain mixture B. Put the mixture B into the ceramic reactor, first pass nitrogen, and after purging the oxygen, start the heating switch of the ceramic reactor. The ceramic reactor was heated up to 600° C. at a heating rate of 10° C. / min and kept for 2 hours to obtain activated material C. When the activation time stops, quickly sink the activation material C into a container filled with liquid nitrogen, and quickly seal the container, place it on a shaker, and shake it for 2 hours to obtain the activation material D. Put the ac...

[0015] Embodiment 2 (comparative example)
[0016] Crush the dried fruit shell to 0.15mm~30.00mm, weigh it for later use. Configure phosphoric acid solution with a mass fraction of 25%. The weighed fruit shell was mixed with the phosphoric acid solution according to the impregnation ratio of 1:2, and left to stand for 2 hours to obtain the mixture A. Weigh phenol equivalent to the weight of 1 / 10 of the mixture A and mix it with the mixture A, put it into a drying oven at 105° C., and dry it for 12 hours to obtain the mixture B. Put the mixture B into the ceramic reactor, first pass nitrogen, and after purging the oxygen, start the heating switch of the ceramic reactor. The ceramic reactor was heated up to 600° C. at a heating rate of 10° C. / min and kept for 2 hours to obtain activated material C. When the activation time stops, quickly sink the activation material C into a container filled with -20°C ice-salt water, quickly seal the container, place it on a shaker, and shak...
Embodiment 3
[0018] Embodiment 3 (comparative example)
[0019] Crush the dried fruit shell to 0.15mm~30.00mm, weigh it for later use. Configure phosphoric acid solution with a mass fraction of 25%. The weighed fruit shell was mixed with the phosphoric acid solution according to the impregnation ratio of 1:2, and left to stand for 2 hours to obtain the mixture A. Weigh phenol equivalent to the weight of 1 / 10 of the mixture A and mix it with the mixture A, put it into a drying oven at 105° C., and dry it for 12 hours to obtain the mixture B. Put the mixture B into the ceramic reactor, first pass nitrogen, and after purging the oxygen, start the heating switch of the ceramic reactor. The ceramic reactor was heated up to 600° C. at a heating rate of 10° C. / min and kept for 2 hours to obtain activated material C. When the activation time stops, turn off the ceramic heating switch, cool down naturally until it reaches room temperature, and then turn off the nitrogen gas to obtain the activat...
